King Crimson

Despite his claim that he was quitting the music business a few years ago, guitarist Robert Fripp has reunited even more surviving members of King Crimson for the group's latest tour. The legendary prog-rock group, best known for its 1968 debut In the Court of the Crimson King, has been sampled by Kanye ("Power") and cited as an influence by acts like the Flaming Lips and RJD2. Here, the group brings its sprawling, conceptual compositions to the Chicago Theatre—get ready for guitar noodling galore.
